In the wake of Travis County District Attorney Rosemary Lehmberg’s DWI case earlier this year — which prompted Gov. Rick Perry to veto state funding for the Public Integrity Unit overseen by her office — an assistant prosecutor now faces a drunken-driving charge.

Lehmberg said in a Tuesday statement that Assistant District Attorney Brandon Grunewald was arrested Sunday for driving while intoxicated and that the Travis County attorney would be handling the misdemeanor case. It is Grunewald’s first arrest, she said.

Grunewald has maintained an “excellent” performance during almost five years in the district attorney’s office, Lehmberg said.

She concluded her statement this way:

“I met with Brandon yesterday to discuss the matter. He will work with his attorney over the next days to determine the best course to dispose of the case. Because the events are so recent, I informed Brandon that I would wait until all the facts are known before making any final decisions, but that it has not been our usual course to terminate an employee for first offense DWI.”

Perry vetoed funding for the Public Integrity Unit criticizing it when Lehmberg refused to resign after her DWI. Her arrest raised particular concern because of her behavior while being detained, which was caught on video.

The unit investigates allegations of wrongdoing by state public officials. If Lehmberg resigned, Perry would appoint a replacement pending an election.
